Abstract
A method of fabricating a recording head is disclosed in which a needle-type control electrode is formed integrally with the substrate. The method includes steps of forming on a substrate a first member layer having a pattern such that the substrate is partially exposed. Forming a second member layer spanning a portion of the exposed substrate and a portion of the first member layer. Then, a needle-type member is formed from the second member layer. Finally, the basic portion of the recording head is completed just by joining the substrate and an overhead plate. Thus, there is no need to join the needle-like control electrode with the substrate. There is no need to position members having critical dimensions with each other.
